Ron Jaworski and Sean Salisbury go inside the game plans for the Broncos and Chiefs.

Sunday's matchup between the Broncos and Chiefs (1 p.m. ET, CBS) features two unbeaten AFC West rivals vying for sole possession of first place.

The Broncos have gotten off to a fast start by playing solid defense and counting on quarterback Jake Plummer or running back Clinton Portis -- depending on which one has been healthy and active. Kansas City has continued to rely on Priest Holmes and its high-powered offense, but has gotten improved play from the defense.
